About
Panagiotis Papagiannis is a leading expert in medical physics, with a primary focus on the dosimetry of small and nonstandard radiation fields used in advanced radiosurgery systems. His major contributions center on the precise measurement and calibration of output factors for the CyberKnife robotic radiosurgery system, a technology critical for treating tumors with high accuracy. In his highly cited 2012 work (64 citations), Papagiannis experimentally determined correction factors for microchamber and diode detectors to enable accurate output factor measurements for the CyberKnife’s variable aperture iris collimator, addressing a key challenge in small-field dosimetry. Earlier, in a 2010 paper (61 citations), he implemented a novel dosimetric formalism for nonstandard fields, adapting reference dosimetry protocols to the unique geometry of robotic radiosurgery. These studies have had a profound impact on clinical practice, providing essential data for treatment planning and quality assurance. His work is widely recognized for bridging the gap between theoretical dosimetry and practical application, making him a trusted authority in the field of stereotactic radiosurgery and small-field radiation measurement.
